Quantitative 23Na-MRI: From Pre-Clinical to Clinical Practice
(2010)Quantitative 23Na-MRI (qNa-MRI) is a non-invasive technique which allows for measuring subtle changes in the Tissue Sodium Concentration (TSC) after ischaemic stroke. Although, an increase in TSC after stroke has been ... -
Quantitative assessment of perceptual, motor and cognitive function in Parkinson's disease and their contribution to freezing of gait
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2016) -
Quantum dot energy relaxation mediated by plasmon emission in doped covalent semiconductor heterostructures
(American Physical Society, 2007)The interaction between interface plasmons within a doped substrate and quantum dot electrons or holes has been theoretically studied in double heterostructures based on covalent semiconductors. The interface plasmon modes, ... -
Quantum effects in the Brownian motion of a particle in a double well potential in the overdamped limit.
(2009)Quantum effects in the noninertial Brownian motion of a particle in a double well potential are treated via a semiclassical Smoluchowski equation for the time evolution of the reduced Wigner distribution function in ... -
Quasiprobability density diffusion equations for the quantum Brownian motion in a potential
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2007)Wigner's [E. P. Wigner, Phys. Rev., 1932, 40, 749] representation of the density operator as a c-number quasiprobablity distribution in phase space allowing quantum mechanical averages involving the density matrix to be ... -
Radar, TV, and Cellular Bands: Which Spectrum Access Technique for Which Bands?
(2014)Opportunistic access has been considered by regu- lators for a number of different spectrum bands. In this paper, we discuss and qualitatively evaluate techniques used in the discovery of spectrum opportunities, also ... -
Radical plumbers and playpumps
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2011)This thesis analyses the PlayPump, a water pump powered by a children's roundabout, which is designed for use in the developing world. The PlayPump is analysed as an example of 'design for development', an area of current ... -
Radio Access Network and Spectrum Sharing in Future Mobile Networks
(2016)Future mobile networks will be characterized by wide-spread resource sharing, and a more nuanced view of what it means to offer a mobile service. The traditional view of a mobile network as a system that simply delivers ... -
Radio transmitter fingerprinting: A steady state frequency domain approach
(IEEE, 2008)We present a novel technique for radio transmitter identification based on frequency domain characteristics. Our technique detects the unique features imbued in a signal as it passes through a transmit chain. We are the ... -
Raman and Fourier transform infrared study of substitutional carbon incorporation in rapid thermal chemical vapor deposited Si 1-x-yGexCy on (1 0 0) Si
(2010)We report on a detailed study of the dependence of the vibrational modes in rapid thermal chemical vapor deposited Si1?x?yGexCy films on the substitutional carbon concentration. Si1?x?yGexCy films were investigated using ... -
Raman investigation of different polytypes in SiC thin films grown by solid-gas phase epitaxy on Si (111) and 6H-SiC substrates
(2010)Raman spectroscopy was applied to investigate a series of SiC films grown on Si and 6HSiC substrates by a new method of solid gas phase epitaxy. During the growth characteristic voids are formed in Si at the SiC/Si ... -
Rapid Thermal Oxidation of Ge-rich Strained Layers
(IEEE, 2004)In this paper, we repolt for thejirsr time the electrical properties ofultrathin oxides grown using rapid thermal oxidation (RTO) on strained Ge-rich layers on relaxed-SiGe buffers. Rapid thermal oxidation on strained ... -
Re-Engineering Rate Distortion Optimisation in Modern Video Codecs Using a Per Clip Approach
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2023)The majority of internet traffic is video content. This drives the demand for video compression to deliver high quality video at low target bitrates. Optimising the parameters of a video codec for a specific video clip ... -
Real-time out-of-band interference reduction for OFDM-based systems
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2012)Interference reduction for OFDM-based systems is of increasing interest in new technologies such as dynamic spectrum access networks. In the past decade, many approaches have been proposed for reducing the interference of ... -
Real-time zero-day Intrusion Detection System for Automotive Controller Area Network on FPGAs
(2023)Increasing automation in vehicles enabled by in- creased connectivity to the outside world has exposed vulnerabilities in previously siloed automotive networks like controller area networks (CAN). Attributes of CAN such ... -
